Thread: Oil light flashing intermitently on dash TD5

the oil pressure sender is located at the back of the oil cooler behind the turbo/engine pipe
as for the start and power issue have you ever replaced the fuel pump

No. I think the fuel pump is solid. It did pump a lot of air(was noisy) after the FPR was returned to the head and still makes a fair bit of noise at times when first turning on the ignition. I am having a great deal of trouble getting the thing bled.

I will have a good look at the oil sender in the morning .It is just where I stuck the pressure washer , may have some damage there.
Thank you for this info. I sort of remembered seeing it there but not being totally up on the workings of this piece of "Pommie equipment" I was not sure.
As an ex pom ( can't help where I was born) I marvel at some of it's weird engineering.Who in their right mind builds a water pump and slams an oil filter right up against it so you have to remove the filter to fix the pump...I'm sure you get my drift.
It is mind you, a GREAT drive.

Assuming the car was running OK before. , you have potentially changed the parameters on 4 area's
Cam timing , injector washers/orings , injector clearances and depending on how you removed/ replaced fpr, potential for getting fuel hoses the wrong way round
Would hazard a guess at injector copper washers and/or cam timing
Water or earthing issue re: oil light

Injectors have new washers.
I was concerned the three bolts on the timing chain were showing a slight overlap of the washers . ( there were slight marks where the washers were not in exactly the same place that they had been before the pull down) They were about three sixteenth of an inch different
The car went really well before the head job.
The fuel pipes are correct.

My suggestion is undo the oil switch plug and have a good look at the wire inside the conduit.
It is a common issue that the conduit gets brittle and the wire rubs through the insulation.
It then earths and brings the light on.
Also check the wire isn't pinched as the heads been off.
The black wire in there does nothing and goes nowhere too.







For the running recheck you cam timing.
They aren't the easiest to get right.

In the cold light of morning , I have just remembered wiretying a conduit up to the steel pipe behind the head. I did not see where it went but thought it might rub if left laying on the bell housing.
I would lay money that is what the problem is.
Thanks guys.
I will let you all know the result soon.
Regards Nick.

O.K. All is good.
snipped off the cable tie and no more oil light flashing.
Mind you ,I still have a lot of trouble starting it
Don't seem to be able to clear the fuel line of air.
